• A. 0 seconds
• B. 2 seconds
• C. 5 seconds
• D. 7 seconds

Answer: (B)

Capillary refill time measures how quickly blood returns to the capillaries after blanching the mucous membranes. In a healthy, well-perfused animal, the color should return within about two seconds, reflecting adequate peripheral blood flow. If the refill is slower than this, it suggests reduced perfusion from dehydration, shock, vasoconstriction, or other circulatory issues. Times much shorter or longer than this aren’t typical normal findings, so about two seconds best matches a normal CRT for a healthy animal.
